Abstract

Background: Twenty percent to forty percent of individuals undergoing coronary artery bypass grafting develop atrial fibrillation as a complication of the procedure. Over a 6-month follow-up period, left atrial (LA) strain was a reliable predictor of AF recurrence following cardioversion.

The work aims: to assess the relationship between the development of postoperative atrial fibrillation (POAF) in coronary artery bypass grafting (CABG) patients and LA function as assessed by 2D speckle tracking echocardiography.

Patients and Methods: From November 2022 to August 2023, Al-Azhar University Hospital Outpatient Clinics evaluated 50 patients with multivessel coronary artery disease for elective coronary artery bypass surgery.

Results: There was a strong connection between POAF and the LA conduit, the contractile and reservoir strain, the age, the peak A wave, the E/A ratio, the peak E, the E/E ratio, the LA volumes (V max, V min, and pre-A volume), the LA volume index (LAVI), and the LA diameters. There was no statistically significant relation between POAF and demographic data (sex, BMI, BSA, DM, HTN, and smoking), LVIDd, LVIDs, IVSd, PWDd, peak E wave, and E deceleration time.

Conclusion: Speckle tracking echocardiography serves as a reliable, non-invasive tool for assessing atrial mechanical dysfunction in individuals undergoing CABG. This might aid in the detection of patients at high risk for POAF and the avoidance of POAF following CABG.
